Realme C75 5G (64GB / 4GB RAM) specifications and in-depth review

Realme C75 5G (64GB / 4GB RAM)

Manufacturer: Realme

The Realme C75 5G is a 5G-capable smartphone built around a 6.67″ IPS LCD panel running at a 120Hz refresh rate, offering reasonably fluid visuals for everyday use. It carries an IP64 rating for dust and water resistance, sits at 7.9 mm thick, and weighs 190 g, making it a moderately slim handset with a practical level of environmental protection.

Under the hood, the device runs on a MediaTek Dimensity 6300 octa-core chipset fabricated on a 6 nm process, paired with 4GB of LPDDR4 RAM and 64GB of internal storage that can be expanded via a microSD slot. The 32 MP main camera supports phase-detection autofocus, HDR, and slow-motion video at 1080p 30fps, while the front houses an 8 MP shooter. Powering the phone is a 6000 mAh battery with 45W wired fast charging, and connectivity options include 5G, NFC, Bluetooth 5.3, Wi-Fi 5, USB Type-C, and a 3.5 mm headphone jack. The device ships with Android 15 out of the box.

Pros
  • The 6000 mAh battery paired with 45W wired fast charging provides substantial capacity with relatively quick top-up times, and a charger is included in the box
  • IP64 certification offers genuine protection against dust ingress and water splashes from any direction, adding practical durability to an otherwise standard build
  • The 120Hz refresh rate on the IPS LCD display delivers noticeably smoother scrolling and navigation for everyday tasks
  • 5G connectivity is supported alongside NFC, Bluetooth 5.3, dual SIM, and expandable storage via a memory card slot, covering a wide range of connectivity needs
  • The main camera includes phase-detection autofocus, continuous autofocus during video, HDR mode, slow-motion recording, and a solid range of manual controls including ISO, exposure, focus, and white balance
  • Android 15 brings a comprehensive set of privacy controls, including app tracking blocking, clipboard warnings, and camera and microphone access management
Cons
  • The 720 x 1604 px resolution results in a modest pixel density of 264 ppi on a 6.67-inch panel, which limits sharpness compared to higher-resolution displays
  • No optical image stabilization is available on the main camera, and video recording is capped at 1080p 30fps with no HDR10 or Dolby Vision recording support
  • Audio output is limited to a single speaker with no stereo capability, and none of the advanced Bluetooth audio codecs such as aptX, aptX HD, or LDAC are supported
  • The gyroscope is absent, which restricts certain motion-based apps and features that depend on rotational sensing
  • Wireless charging is not supported, limiting charging to wired connections only
  • Direct OS updates from the vendor are not available, meaning software updates are not delivered through the manufacturer's own update channel
Who is this for?

This device is a solid fit for everyday users who prioritize battery endurance, given the 6000 mAh cell with 45W fast charging that handles extended daily use without frequent top-ups. The IP64 rating makes it a practical choice for people who work or spend time outdoors and need basic protection from dust and water splashes. Those who value smooth general navigation will appreciate the 120Hz IPS LCD display, and users who want broad connectivity in a single handset will find the combination of 5G, NFC, dual SIM, and expandable storage genuinely useful for daily communication and light productivity tasks.

Who is this NOT for?

Users who regularly shoot photos or video in challenging conditions will find the setup limiting, as there is no optical image stabilization, no RAW output, and video is capped at 1080p 30fps without HDR10 or Dolby Vision recording. The 720p display resolution and absence of HDR support make this a poor match for anyone who consumes a lot of streaming content and values sharp, color-accurate visuals. Similarly, users who rely on motion-sensitive applications — such as certain games or augmented reality tools — will be hindered by the lack of a gyroscope, and those seeking a rich audio experience will be disappointed by the mono speaker output and the complete absence of high-fidelity Bluetooth codecs.

Final Verdict

The Realme C75 5G is a straightforward 5G handset built around two clear strengths: a 6000 mAh battery with 45W fast charging and a practical IP64-rated design that holds up in everyday outdoor conditions. Running Android 15, it covers the essentials well — dual SIM, NFC, expandable storage, a 120Hz display, and a reasonable camera feature set for casual shooting. Where it falls short is in areas that matter to more demanding users: the 720p resolution limits display quality, the single-lens camera lacks stabilization and tops out at 1080p video, and the absence of a gyroscope and stereo speakers narrows its appeal for media and gaming. For users whose primary needs revolve around connectivity, day-long battery life, and reliable daily performance, the C75 5G delivers a competent and well-rounded package; those seeking a more refined multimedia or photography experience will need to look elsewhere.
